Abstract: Thin sheets of metal foil are dispensed one-sheet-at-a-time by a dispenser. Differentially-sized stacks of foil sheets are held in correspondingly sized open-top reservoirs in a container. Removable paddles fit within the open tops of the container's reservoirs. The paddles have contact adhesive, typically non-drying electrician's clay, on their underside surfaces. The uppermost foil sheets within the reservoirs adhere to the paddles. Each paddle and its adhered foil sheet is extracted from the container, turned over, and maneuvered, foil sheet uppermost, into position below a lock of a subject's hair. In this position the hair lock is treated, typically by brushing with liquid hair coloring, while the foil sheet pools the liquid in contact with the hair. The thin foil sheet is peeled from its paddle carrier and folded around the hair lock. The treatment liquid is maintained in contact with the hair lock by the folded foil sheet.
